As willbe seen, the small drill is on the same center line as the spindleof the machine and the arrangement is such that no end thrustis conveyed through the speeder. The gears and pinions withinthe case are arranged in pairs and side strains are entirely elim-inated.

This islong enough to reach to the column in the case of a large up-right drill, but when used on a radial drill some rigid stop mustbe provided, or the bar can be held by the hand, if desired. Inthe drill speeder shown the feeding of the drill is done by themechanism on the machine. Other styles, however, have sensi-tive feed levers that permit the feeding through a racked sleevewithin the speeder Application of Drill Speeder to Upright Drill. HYDRAULIC FORGING AND BENDINGPRESS The illustration shows a hydraulic forging and bending pressfor locomotive and car shop work, such as the making of equal-izer bars and other heavy bending and straightening, which iscommonly done in a geared type of bulldozer. This machine willhandle a wide range of work, and the application of the power isdirect and positive. A further advantage claimed for it is thatof being safe from breakage, due to the operator putting in work return stroke and ample power for stripping the dies. The fieldfor such a press in a locomotive or car shop is large, and it isclaimed for this machine that it will accomplish such work atminimum cost. This press is manufactured by the Chambersburg EngineeringCompany. Chambersburg. Pa.
